The instructions that came with my K-Type are either lacking or intended for a different crank. The one I have includes a preload collar on the NDS which doesn't even appear in the instructions. What is the appropriate installation procedure and method for setting preload? Should I use grease or loctite on any bolts/interfaces?

I received instructions from KCNC. Posting them here in case anyone else is in search of this:
1. Loosen small bolt on red preload collar and install on non-drive-side crank arm.
2. Apply anti-seize grease on axle bolt, splines and arm sockets of the drive side.
3. Tight the drive side axle bolt, tight it to dead end.
4. Apply anti-seize on axle.
5. Put the axle through BB.
6. Again, apply anti-seize grease on bolt, splines and arm socket of non-drive-side.
7. Tighten the non drive side axle bolt to dead end.
8. Adjust the final gap/clearance on red spacer/clamp bolt. You don’t necessary need to make it very tight as long or the BB bearing can overload. (They also gave me a guideline of 3Nm.)
The anti-seize coating seems to help eliminate some clicking sounds I was getting when I used standard grease.

On my RD-2 crankset the red pre-load collar is attached to the NDS crankarm.

Sorry, I mistyped. Preload collar should be installed on NDS arm as yours is.
What does your collar say? I can not make it out. "This gap must not...". Mine does not include this warning, whatever it is.

"This gap must not fully close"
